The Birket
Siwa is the visually most attractive of the two salt lakes of Siwa. It
starts where the palm groves end, and it is framed by table-top
mountains. The largest is the Adrar al-Milal, or White Mountain.
Today the lake is receding and it is becoming more and more saline. Much
of it has now a surface of thick crust.
Birket Siwa is best visited as a part of a trip to Fatnis Island. There
are passageways running from the island and out into the lake. This does
not give the impression that you cross the lake, there are less and less
clear borders between lake and land.
